Изобретение относится к режущим инструментам для обработки металлов и изделии из пластических масс. Цель изобретения - упрочнение режущего зуба, увеличение стойкости полотна и плавность работы. Ножовочное полотно содержит режущие зубья, чьи режущие кромки по торцевой поверхности выполнены с углом наклона 4-6o, на боковой поверхности имеется направляющая ленточка шириной d = (0,2-0,3)t , где t - шаг зубьев, профиль зуба выполнен с отрицательным передним углом 4-6o и задним углом 36-38o, а высота зуба составляет 0,9t.The invention relates to cutting tools for metal processing and plastic products. The purpose of the invention is the hardening of the cutting tooth, increasing the durability of the blade and smooth operation. The hacksaw blade contains cutting teeth, whose cutting edges on the end surface are made with an angle of inclination of 4-6 o , on the side surface there is a guide tape of width d = (0.2-0.3) t, where t is the tooth pitch, the tooth profile is made with a negative rake angle of 4-6 o and a rake angle of 36-38 o , and the height of the tooth is 0.9t.
